Y = 2x + 2
Y = 2x -
Subtract

0 = 2

This makes no sense meaning the lines are parallel. Therefore there are 0 solutions.

0 solutions. Using the slope-intercept form y=mx+b, you can tell that the slope m for both lines is 2. Two lines that have the same slope are parallel. Since they are parallel, they don't intersect, hence there are no solutions to the system.

I got x= 12 but Ik that’s wrong
serg [7]

Answer:

x = 15°

Step-by-step explanation:

Due to Alternate Exterior Angles, we can tell that '5x = 75'. Now, let's simplify x.

=> 5x = 75

=> 5x/5 = 75/5

=> x = 15

Therefore, 'x = 15°'

Find the 30th derivative of y=cos(2x)
Sladkaya [172]

I got this answer from someone else so I’m not sure this is correct but I really hope it helps...

Step-by-step explanation:

Look for patterns in the derivatives.

y=cos2x

y'=-2sin2x

y''=-4cos2x

y'''=8sin2x

y''''=16cos2x

Notice that sin and cos alternate every derivative. Also, they alternate positive and negative every 2 derivatives.

The constant is just 2^(derivative#).

Every odd derivative has sin and every even derivative has cos, so you know that the 30th derivative will be cos.

If you follow the pattern of negatives and positives, you find that the 30th derivative will be negative.

y^(30)= -2^30cos2x

y^(30)= -1073741824cos2x

Which expression correctly shows 2x³y - 2y factored completely?
OverLord2011 [107]

Answer:

2y(x-1)(x^2+x+1)

Step-by-step explanation:

~~~2x^3y-2y\\\\=2y(x^3-1)\\\\=2y(x-1)(x^2+x+1)~~~~~~~~~~;[a^3-b^3 = (a-b)(a^2 +ab+b^2)]
